Version 9 will work with AC below the Medical version.
Only the Medical version in 10 works with AC.
Of course version 10 is supposed to be better than 9 (I have not used v10)
One advantage of the medical version is that you can put it on as many computers as you wish (only 1 user though.)With lesser versions, you need a separate copy for each machine.
Do you really need to be certified???? I have no idea.
